Docker container MySQL enables binlog and scheduled backup

In order to ensure mysql Data integrity of database , In addition to the database data linked to the host for persistence , Still need to be done binlog And regularly backup data

1, add to mysql Files mapped to docker-stack In file

      # Specify on binlog Configuration file for 
      - /home/test/binlog/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf
      # Specify the scheduled task execution of the backup database shell file 
      - /home/test/binlog/mysql-dump.sh:/home/app/mysql-dump.sh
      # Specify scheduled backup to store files 
      - /home/test/binlog/mysql_dump_file:/home/app/sql_backup

mysqld.cnf The configuration file is as follows ： On is specified binlog And storage binlog Path to file （ This path needs to be attached to the host ）

2, After starting the project, enter mysql In container : 

1. Execute command update linux library      ： apt-get update
2. Install the scheduled task tool ： apt-get install -y cron vim
3. Edit the task by command ： crontab -e
4. Add the task command ： 59 23 * * * /bin/sh /home/app/mysql-dump.sh
5. start-up crontab ：service cron start

       

Here we are ,docker Containers mysql Turn on binlog And scheduled backup processing
